    Hey fellow forum members.

    Many of you recently watched a video i put together about installing a Nexus 7 in the dash of a truck.

    Question for the forum....

    We want to install a backup camera in the truck using the display of the Nexus 7. Most of the back up cameras are using a RCA video output. Any thoughts on how we can get the video output from the camera to display on the Nexus 7?

    For those that haven't watched the videos yet (or want a refresh), here are the YT videos.

    What about a wi-fi camera? It can be used as a backup camera and transmits video using wifi.

    I was thinking bluetooth webcam off the shelf but wifi might be better especially if you can wire power.

    What app would we need to launch in order to see the video transmitted via WiFi? I imagine something similar to Skype...?

    We would want the back up camera to appear when the car is put in reverse, so we would need the app to open fast... (we don't want to put the car in reverse and wait 5-10 sec for the app to load/video to connect).

    Good point. I was thinking of those X10 cameras people use around the house. You can do split screens when you have more than 1 camera. Each camera has it's own IP address, and a mini web server. So you can point the browser to the IP address of the camera and see the video. So it should load fast. I'm not sure how you would trigger the browser to show when you put it in reverse though.

    Good question. How does the OP plan to tell the Nexus the vehicle is in reverse? Can't use the accelerometer because you should look before you start backing up.

    They would need to initiate something on the Nexus, or have an app created that all it does is listen on a specified port. When it sees activity then have it launch the browser with the appropriate IP address. But that still leaves the question of how to get that info to the Nexus. They can know when it's put into reverse, maybe tie into the 12v for the reverse lights. And that 12v can trigger a relay that does something. I don't know, just thinking out loud.

    It is a good question indeed. We are still brainstorming this and figuring out if there is a way to do it.
    We had looked at plug in launcher apps (like the appropiately named app Plug In Launcher) and have a relay or switch in line on one of the input connectors (usb/headphone/etc).

    So the thought would be when the car is put in reverse, it completes the connection to input connector (like USB), launches the app which would display the video signal.

    IP Cam Viewer (free or Pro version) would work great for many IP cameras, but I don't know how to make it automatically launch when you start to back up. I forget how many cameras the free version supports, but the Pro version supports as many as your device can handle (limited only by speed, network bandwidth, space on the device, etc).

    Hey guys,

    I'm starting to research doing a similar thing in my new T5, did you solve the issue with connectivity for a reverse camera?

    Can we find a bluetooth webcam? If we can find one, we will power it only when in reverse, and it will pair automatically with the tablet. Using an application like AutomateIt, we can launch a specific application when it pairs, so voila. But where to find a bluettoth camera? I was thinking at one like this: Looxcie LX1 Wearable Bluetooth Camcorder 0859781002006 | eBay. But we nned something good in low light....

    I'm not sure it works, but maybe you can use some of these OBD devices to know it the vehicle is in reverse. There are some bluetooth options.

    I saw in your video that you have optical input. You could take advantage of that using a hdmi audio splitter to get surround sound directly from Nexus 7. It will work only if the media you're playing have surround sound, obviously.

    I'm toying with a similar idea, again in a T5.
    If going down the wifi route, there are a number of ethernet/wifi digital I/o modules about. All that would then need would be a small app to monitor the input for the signal from the reversing lights.

    A usb cam might be more reliable than Bluetooth if it will work on the N7. Why not just run the app so the camera is in the last run apps? Then it would always be there when you want it.

    You can get a WIFI backup camera, and use your Android phone as display. It is WIRELESS.
    Check the demo video out, and see how this Backup Camera for Android works

    New NEXUS 7 had embedded UVC driver on Android 4.3 OS.
    That means uvc webcam can directly plug into your Android 4.3
    And it will also work without "ROOT"

    Please download apk "dashcam" from google play

    1. For backup camera (RCA output camera)
    FEBON100 UVC CVBS grabber card


    2. For HD HDMI car recorder camera (720p hdmi)

    So im planning to do the same, though I haven't decided which tablet i want to use. My plan for the reverse camera is this ~ using the camera (link above - 4ucam) and its wifi adapter, I power them off the reverse lights, with a secondary switch for full time operation. When the reverse lights come on, it begins to transmit wifi. Nexus connects automatically, I then have an app-based trigger (automateit.apk) to launch the reverse cam. App

    Did you ever get the 4ucam to work? Is there an issue with being connected to two WiFi networks? One for tethering will cell phone and the other for the camera?

    Also could you achieve this by using a wireless 2.4ghz camera with an EasyCap instead?

    why not just pull up the browser and leave it up, and minimize when done?

    Mine is often tethered to my mobile phone. Perhaps an app that would auto-launch tether when near the vehicle? I know if I leave tether on on my phone it will auto connect but I really don't want to do all that (and run up my tether data).

    I was just curious how/where one might mount the camera inconspicuously(hidden)? Which camera model to use? Guess a regular webcam would work, right? Power for the camera??? USB with extra long cable to the cigarette lighter jack???

    IDEAS???

    I am looking for a similar solution. Cost is my major concern. I can purchase a stereo with a 6" display, and back-up camera ready. But to get the backup camera installed will cost around $200.

    So, I see WiFi back-up cameras going for under $50. And if I limit the choices to something that looks a little higher quality, I find one for $130 at RVS-020813 | WiFi Backup Camera System

    I have a SUV, and ideally I would like to install it inside the car, at the top of the rear window. But, I have not idea if that will be workable. Reflections in the glass may be a problem.

    My major concern is the time involved with getting the application to display the image. For example, I get in the car, and turn it on,. Then, I start the phone app. How long will I need to wait for the the image to show up?

    Thanks for any advice.

    I have found generic rear view cameras on Amazon and eBay for as little as $5 - $25 which all show nearly identical specifications only varying in form/mounting method, focal length/degree of view (110° - 180°), listed Water Resistance Rating (IP66- IP69).

    Also, Wi-Fi transmitters (which are made to connect to these cameras) for as little as $6 - $40.

    These create a Wi-Fi network which you then connect your phone or tablet to, open any one of the many IP camera apps and you're golden.

    Depending on how you want the camera to function you can wire it up to begin transmitting when the vehicle is shifted into reverse [wire the transmitter to the reverse lights] or have it transmitting constantly [wire to the running lights] which might result in faster initialization times.

    I will admit I have seen cameras and Wi-Fi transmitter setups listed at much higher prices but not listing any better specifications. 4ucam wants $130 for the same things you can find for less than $50.

    Just came across your site as I was downloading a manual for the RVS-020813 backup camera and I just finished the installation. Camera works great, I wired the camera to constant ignition so whenever i goto the GoVue app, the camera image instantly appears on my Note3 with no delay. Hope my input helps.

    Thanks for the update. It is good to hear that it is a viable solution.

    I ended up going with the direct-wire solution. That way I was certain to get a picture right away. My installer was also quite leery about the idea of using WiFi, saying they often are unreliable. My Bluetooth audio interface is certainly a testimony to why Bluetooth would not be a viable way to connect a backup camera. It is not unusual for the car stereo to take half a minute to connect to my phone. I would not want that long of a delay in a backup camera system.
